no kooks are here to stay but I just read where their results are all over the place

What makes you say that? Each set of KOOKS headers is identical to the next and their gains are repeatable each time. I think the variable is the tuner and/or the difference between automatics and standard transmissions aka drivetrain loss.

We sell and install a ton of headers here at JDP and KOOKS headers are hands down some of the nicest headers available; that's why we use them on 90% or more of our builds.

what are some of the results of the automatic Kooks you guys have installed. I havent seen many people running off road instead of cats and thats what im interested in. I have yet to hear how it would sound and its performance

Im looking towards the kooks, the trim in the belly pan isnt bad, though I would prefer to not to alter it. It for the performance and sound. Not going to let the belly pan stop me from what I want to do. Unless someone wants to sell me their Pfadt Tri Ys lol

Don't be to sad. I recently bought, installed and drove with pfadt headers. Car was wrecked which puts me a square one. Even if they were still available I would be going in a different direction this time around.

Just curious why you would not want the pfadt again. Looking to buy headers so just curious.
Thanks

We haven't done any with headers alone, so I can't really give a fair comparison, but they are good for roughly ~40 WHP with tuning and the gain only gets better when other mods are introduced. I suggest going with catted connection pipes as off-road pipes tend to be raspy.

Though it might be raspy, I just wish to hear it somehow so that I could compare them and see if I want them. Its between kooks and american racing headers.

I couldn't find a thread on this so I don't know if it's been broadcast or not. Apparently Pfadt has gone out of business. I was going to order a package from Jannetty and they told me the bad news. So my question now is what headers do I go with? I am so bummed that I almost don't even feel like going through with my build. Any suggestions?

We used Stainless Works 2" with there black Ceramic coat on our customers Record setting bolt-on's ZL1 (10.14 @ 137.13)! Great headers and fit great too. I highly recommend them!

Here is the pull from when my ZL1 was being dyno'd. This is with kooks 1 7/8 LT headers, no cats and roto fab cai. The quality of the video kinda sucks but hopefully it helps you decide. If I had to do it again I would pick kooks again.

finally my prayers have been answered. Im probably going to go with Kooks with no cats
